What if we could use a hacker’s favorite buzzwords — blockchain and decentralization — to fight back against ransomware? As a cybersecurity grad student, I often build and test real-world attack scenarios. But this time, I wanted to take it one step further. Instead of just detecting or analyzing ransomware, I wanted to create a backup system that could survive it completely and even recover files without paying a dime. And it worked. Using IPFS for file storage, a smart cont

In today’s digital world, anyone can alter an image with just a few clicks. Because of this, I wanted my digital forensics project to focus on a real investigative challenge: how can we scientifically determine whether an image is authentic or manipulated? Using a combination of forensic tools and structured analysis, I examined how metadata, compression signatures, pixel inconsistencies, and cloned regions expose tampered photographs. The posters I created visually summariz

Augmented Reality Plant Disease Detection Repository: https://github.com/prabhu31297/Plant-Disease-Detection-using-OpenCV Introduction In 2019, during the final phase of my undergraduate degree, I set out to build something that was both technically challenging and directly useful in the real world. Agriculture is still the backbone of India’s economy, yet many farmers lose a significant portion of their harvest because plant diseases are detected too late or misdiagnosed. Di

In this project, I wanted to take something simple and visual – a Tetris-style web page – and use it to practice real DevOps on AWS : Containerize an app with Docker Push images to Amazon ECR Run containers with ECS Fargate Expose it to the internet Automate builds and deployments using CodeBuild + CodePipeline Deal with real-world issues like ARM vs AMD64 images, security groups, and image pulls The result is a small but production-style pipeline that you can reuse for any

Imagine losing your keys in a coffee shop. Hours later, you're staring at your iPhone, which pinpoints their last known location on a map—thanks to a tiny AirTag and an anonymous stranger’s iPhone. But here’s the catch: Neither Apple, nor that stranger, nor even the AirTag itself knows your keys were found. At least, that’s what the marketing says. For our graduate project in Network Security , I dissected the Apple AirTag’s cryptographic design . We explored public resea
